NITQED STATES ATENT AXLE-LUBRICATO R.

SPECIFICATION forming part of Letters Patent No. 319,679, dated June 9, 1885.

Application filed July 18, 1884. (No model.)

To all whom, it may concern:

Be it known that I, J OSEPH M. DENNEY, of Wartsburg, in the county of Walla Walla, Washington Territory, have invented a new and Improved Axle-Lubricator, of which the following is a full, clear, and exact description.

The invention consists of the combinations of parts and their construction, substantially as hereinafter fully set forth and claimed.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal sectional elevation of a hub provided with my improved lubricating device. Fig. 2 is a longitudinal elevation of the screw-tube and its cap. Fig. 3 is a modification of the device. Fig. 4 is a cross or horizontal section of the same.

The tube A, provided with an external lefthand thread, is screwed radially into the hub B a short distance from the inner end, the threaded tube A extending from the surface of the hub to the bore of the same. At its outer end the threaded tube is provided with a fixed collar, 0, which rests on the outer surface of the hub, and beyond the nut aninternally and externally threaded neck, D, proon which a screw-cap, E, is screwed to close the outer end of the tube and prevent dust, &c., from passing into the same.

I have provided the internal screw in the neck to permit screwing a plug in the outer end of the tube to close the same in case the cap E islost. Thick axle-grease or waste saturated with oil or any other suitable lubricant is filled into the tube and passes from the inner end of the same upon the axle F.

The tube A and its neck D are provided with reverse threads, to permit unscrewing the cap without unscrewing the tube and to unscrew the tube without unscrewing the cap.

In the modification shown in Fig. 3 a rod or stem, G, is screwed to the top and projects down from the under side of the same, which rod prevents the cavity from being filled with dirt.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- The combination, with the hub B, of the externally-screw-threaded tube A, provided with the fixed collar or enlargement O and with an externally and internally screwthreaded neck, D, the internal screw-threaded portion of said neck beingadapted to receive a plug, and the external screw-threaded portion thereof being fitted with a cap, E, substantially as shown and described, and for the purpose set forth.
